Schwab error message "This import was unsuccessful" attempting to download 1099

If you get the error message in the title then it is my understanding that Turbotax only allows download of 1500 line items or less. This means even if you have less than 1500 trade,s but they fill in multiple lots, then this counts towards this limitation. 

Any mildly active trader will easily surpass 1500 line items. Turbotax is of no help and they market this premier edition to help people with trading activity without letting you know of their severe limitation.

Anyone else getting this specific error message and, if so, what are your options other than manually typing in all the trades?
